Instructions for using pkg/ptracers to compute tracer |

Green's functions for Gruber's ocean inversion project |

(see quercus.igpp.ucla.edu/OceanInversion/ for details). |

|
| 8 |
Preprocessed OceanInversion input files are available |
| 9 |
under directories region_mask, takahashi, and |
| 10 |
atm_co2 in this package. All netcdf input files |
| 11 |
have been converted to binary format in order to avoid |
| 12 |
having to link netcdf library with MITgcm code. See |
| 13 |
respective README files in each directory for details. |

|
| 16 |
=============================================== |
| 17 |
First check that pkg/ptracers works OK by using |
| 18 |
salinity initial and boundary conditions |
| 19 |
=============================================== |
| 20 |
|
| 21 |
1 ===> get MITgcm code from cvs repository |
| 22 |
|
| 23 |
CVSROOT=:pserver:cvsanon@mitgcm.org:/u/u0/gcmpack |
| 24 |
cvs login ( CVS password: cvsanon ) |
| 25 |
cvs co MITgcm |
| 26 |
|
| 27 |
2 ===> put MITgcm_contrib/ocean_inversion_project in MITgcm directory |
| 28 |
|
| 29 |
cd MITgcm |
| 30 |
cvs co -d ocean_inversion_project MITgcm_contrib/ocean_inversion_project |
| 31 |
|
| 32 |
3 ===> compile and link |
| 33 |
|
| 34 |
cd bin |

cp data.ptracers.test data.ptracers |
| 53 |
mitgcmuv > output.txt |
| 54 |
|
| 55 |
5 ===> check that PTRACER output and salinity output are identical. |
| 56 |
|
| 57 |
diff PTRACER01.0000000020.001.001.data S.0000000020.001.001.data |
